Application' filed May 3,

This invention relates to belt splicers or fasteners and is designed primarily for `securing the ends of a power belt, such asis employed in connection with variable speed transmission mechanisms, said belt having la series of transverseblocks thereon, with friction pads on the ends thereof.

One feature of the invention is in so constructing the fastening mechanism that Ait may be readily manipulated for securing the ends of' the belt together, even when thev ata " in position on the transmission mechanism.

A further feature of the invention is the provision of means for causing the belt to make a uniform bend while passing around the transmission disks.

Other objects and advantages will be hereinafter more fully ,set forth and pointed out in the accompanying specifica-tion.

VInthey accompanying drawing which is made a part of this application,

Figure l is a detail top plan view of the belt lwith parts broken away.

f Figure 2 is an edge elevation thereof.

Figure 3 is a detail sectional view showing the manner of locking the parts of the splicer together, i' Figure 4t is a perspective view of a portion of the belt and splicing elements cooperating therewith.

Figure 5 is a detail perspective view of one end of the belt.

Figure 6 is a detail eleva-tion o-f a slightly modified structure. y

Figure 7 is a similar view of a further modifiedform, and,

Figure 8 is a similar view, partly in section of a still different form of structure.

Heretofore it has been a more or less arduous task to splice the belt around the transmission disks, especially when the transmission mechanism was in use, owing to the limited space to work and the manner v,the belt ends.

yin which the'splicing was done, but with the present devicethese objectionable features are entirely overcome. v -Q In :the present invention thej endsk of the belt l are provided with cross cleats 2 and 3,

which areksecured to the beltin any suit-l able manner, preferably yby rivets 4, there being a sufficient number ofl rivets used to hold the cleats firmly in engagement with On the opposite placed plates 5, preferablyof Vsheet metal, onev below each cleat, .through whichv the rivetsy 4 valso extend, the top lends ofthe .rivets being preferably countersunkv inthe Liside offthef belt l VVare cleats while the ,inner ends of therivets are 1 provided with projecting heads y6, `which preferably seat in' depressions 7 v.formed in the upper face ofbe-lt blocks 48. The outer edges of the-plates are Apreferably curved to conform tothe curvature; ofthe edges of the blocks 8, thus forming a roundingk surface 9, over which the belt may bend as it is passing around 'the transmission disks, lthus avoiding abrupt bends which might tendto form a break in the belt. 7

The blocks Svare of the usual or anylpre- I. .i

ferred construction andpreferably formed of wood, a strap of metall() being'extended over the underface thereof forreinforcing the same. The endsof thefbeltl are secured together by .first drawingrtheends ofthe belt towards each other until the inner faces of the cleats'me'et,- when-a 'channel'bar vl1 is introduced over the cleatsand-bolts l2, introduced through theblock 8 and the channel bar 11, and secured therethrough by means of nuts 13.L The channel bary ll has depending flanges 11v at each edge thereof .Which loverlaps the side edges of the cleats 2 and 3, thus causing the pull or stress of the belt to be exerted solelyagainst-the side edges of the cleats, or ata pointk to withstand the greatest amount of strain without yielding. The strain is also uniformly distributedV throughout the length ofthe cleats.

and channel bar. The meeting edges of the belt ends, cleats' 2 and 3 and plates 5, are recessed as at 14, to provide circular openings for the passage of the bolts 12, when the ends of the belt are brought together, although it will be understood that one of the cleats may be made wide enough to eX- tend over the opposite end of the belt and the bolt openings formed through this wider section.

In applying this device to use, the cleats 2 and 3 and plates 5 are first secured to the ends of the belt, the belt then extended around the pulleys with which it cooperates and the free ends thereof brought together.

rIhe channel bar ll is then introduced over the cleats and the bolts 12, carried by the block 8, introduced through the recesses let and through the channel bar 11. The nuts 13 are then turned onto the bolts l2, thus securely locking the .ends of the ,belt together and the block 8 to the belt.

Asshown in Figure 6 ot thedrawing, the platesf may be dispensed with and a second set of cleats 2l andf placed on the voppositefaces of the belt-,in whichinstance yand 3b are provided with upstanding studs 2c and 3c which enter recesses or openings 11c in thevclamping plate 11d. rlChe cleats andy clamping plates are shown as attached to the outer face of the belt, but it will be understood that they' may be attached to either or both sides thereof, and instead of providing the studs 2c and 8, a plurality of ribs and cooperating recesses may be provided in the cleats and clamping plate. The

`cleats and the channel bars or clamping plates may also be formed in sections instead of in one piece, and practically the same resultsbe obtained. s

It will thus be seen that in view of th simplicity of this device and the manner in which the parts are secured together, the belt may be quickly and easily placed around the transmission disks and the ends thereotsecured together, and that the operation may be performed in a very limited space, as it is but necessary to tighten 'the nuts on the bolts to secure the parts together.

What I claim is: l

l. In a belt splicer,'the combination with a belt and a belt block associated therewith, ot a pair of members at the meeting ends ot the belt, means interlocking with said members for holding them in fixed position, and means for locking said parts together. y 2. The combination with a belt and belt blocks adapted for use in connection with variable speed transmission mechanisms, of a pair of members fixed to the belt adjacent the severed ends thereof, means adapted to span said members for holding the severed ends of the belt together, and means for locking said fixed members and spanning member together. Y

3. In a belt splicer, the combination with a belt and belt block associated therewith, of a pair of cleats adjacent the severed ends of said belt, means for fastening said cleats to said belt, a-channel bar adapted to span said cleats when Vbrought together, and means for locking said bar in position over said cleats.

4. In 'a belt splicer, the combination with a belt, and a belt..block cooperating therewith, ot members fixed to the severed ends of said belt, plates fixed to said belt between the belt and said block, a member adapted to extend over and hold said fixed members in juxtaposition to each other, and ymeans tor locking all of said parts in assembled relation.l Y

5. In a belt splicer, the combination with a belt, and a belt block cooperating therewith, of a pair of cleats adjacent the ,severed ends of said belt, a pair oi' plates also adjacent said severed ends, means tor fixing said cleats and plates to the belt, a channel bar adapted to engage and hold said cleats ad- Yjacent to each other, and bolts for locking all of said parts in fixed relation with each other.V l

6. In a belt splicer, the combinationwith a belt having abutting ends and a belt block associa-ted therewith, of cleats affixed to said belt adjacent said abutting ends, a channel bar extending over the outer iaces and outer side edges oi said cleats and interlocking therewith, and means for locking all of said parts together. i

In testimony whereof I hereunto affix my signature.
